Full-size griddles and long fish pans are what the flex area on the NITP668UC is for. This Benchmark 36 inch flex induction cooktop on 37 inch glass, with Home Connect, was discontinued and Bosch’s US page marks it as no longer available.
Using the flex area like that keeps the electronics underneath busy for long stretches. A cooktop used regularly that way works its cooling system harder than one used with four separate saucepans, which makes the cooling system the part to watch as the cooktop gets older.
A coil module that fails usually appears as a cool spot within the linked area. Heavy griddle plates dragged across the glass can scratch it. We begin a visit by running the flex area for long enough to see how the cooling behaves, then test the coils for cold patches and inspect the glass.
Sustained flex cooking works the cooling system harder than ordinary use, so that is the part to watch as the cooktop ages. Keep the space below clear and let it rest afterward.
Scratches in the glass cannot be polished out. To prevent more, lift the griddle instead of dragging it. If a scratch becomes a crack, the top needs replacing.
Most likely one coil module has failed while the others work. We test the coils separately to confirm, then explain the repair and quote it in writing.
